Tunneling characteristics along the  direction were measured in InsulatorIn junctions as a function of the magnetic field H, applied parallel to the plane of the junction, along the c-axis. The junctions exhibit a Zero Bias Conductance Peak (ZBCP) which splits as . The data is in better agreement with a field-induced idxy gap component than with a Doppler-shift–induced field splitting.
